Description

In Dampf- und Gasturbinen ist, wie bekannt, der Nachteil vorhanden, daß deren inneren Teile, besonders während des Stillstehens, leicht von -Rost angegriffen werden. Um dies zu verhindern, sind bereits Verfahren vorgeschlagen worden. So z. B. hat man versucht, ein nicht rostendes Material für die Schaufeln und die anderen Innenteile zu verwenden. Es war indessen mit Schwierigkeiten verknüpft, ein zur Herstellung der Schaufeln genügend haltbares und nicht rostendes Material zu erhalten. Die Rostbildung entsteht dadurch, daß sich auf den Innenteilen der Turbine während des Still-Stehens, besonders gleich nach der Abstellung der Turbine, Feuchtigkeit in Form von Wasser niederschlägt.In steam and gas turbines, as is known, there is the disadvantage that their internal parts are easily attacked by rust, especially when standing still. Procedures are already in place to prevent this has been proposed. So z. B. Attempts have been made to use a non-rusting material for the blades and the other internal parts to use. It was, however, associated with difficulties in making the Shovels to get enough durable and rustproof material. The rust formation arises from the fact that on the inner parts of the turbine while standing still, especially immediately after the turbine has been switched off, moisture in the form of water precipitates.

Die Erfindung betrifft eine Vorrichtung zur Verhinderung des Röstens der Innenteile derThe invention relates to a device for preventing roasting of the inner parts of the

ao Turbine, indem das Innere der Turbine geheizt wird, so daß ein Niederschlagen der Feuchtigkeit auf den Turbinenteilen verhindert wird.ao turbine heated by placing the inside of the turbine so that a deposit of moisture on the turbine parts is prevented will.

Die Erfindung besteht darin, daß ein Heizelement innerhalb der Turbine oder in deren Auslaß angeordnet ist, wobei das Element jedesmal, wenn die Turbine stillsteht, in Tätigkeit tritt und Luft, welche um die Innenteile der Turbine kreist, erwärmt.The invention is that a heating element within the turbine or in the Outlet is arranged, the element in operation each time the turbine is stopped occurs and heats air that circulates around the inner parts of the turbine.

Dieses Heizelement besteht zweckmäßig aus einem Spiraldampfrohr, das mit einem Dampfkessel verbunden ist bzw. mit der zur Turbine gehörigen Dampfzuleitung, sobald die Turbine abgestellt wird.This heating element expediently consists of a spiral steam pipe that is connected to a Steam boiler is connected or with the steam supply line belonging to the turbine as soon as the turbine is switched off.

Die Zeichnung veranschaulicht zwei Ausführungsformen der Erfindung, wobei Abb. 1 ihre Anwendung an einer Aktionsturbine und Abb. 2 die Erfindung an einer Reaktionsturbine verwendet zeigt.The drawing illustrates two embodiments of the invention, Fig. 1 their application to an action turbine and Fig. 2 the invention to a reaction turbine used shows.

ι bezeichnet die Turbinenscheibe, die mit den Schaufeln 2 versehen ist. Von dem Dampfeinlaß 3 strömt der Dampf durch die Düse 4, treibt das Turbinenrad und wird durch die Aualaßleitung 5 abgeführt. Der die Innenteile der Turbine umgebende Dampf wird an der Abkühlung verhindert, und damit wird auch die Feuchtigkeit durch das in der Auslaßleitung 5 angeordnet&Heizelement 8, das den genannten Dampf heizt, daran gehindert, sich auf die Innenteile niederzuschlagen.ι denotes the turbine disk which is provided with the blades 2. Of the Steam inlet 3, the steam flows through the nozzle 4, drives the turbine wheel and is discharged through the Aualaßleitung 5. The steam surrounding the internal parts of the turbine is prevented from cooling down, and thus the moisture through the in the outlet line 5 & heating element 8, that heats the said steam, prevented from settling on the internal parts.

Dies ist auch der Fall bei der Turbine nach Abb. 2, wo der Dampf in die Turbine durch Düsen einströmt und das Turbinenrad bzw. die Turbinentrommel 1 treibt, wonach der Dampf, während er Energie abgibt, das Schauifelsystem 12 durchströmt und in den Ablaß s gelangt, wo das Heizelement 8 angeordnet ist.This is also the case with the turbine according to Fig. 2, where the steam enters the turbine Nozzles flows in and the turbine wheel or the turbine drum 1 drives, after which the Steam, while giving off energy, flows through the rocking system 12 and into the Drain s arrives where the heating element 8 is arranged.

Das Heizelement kann an irgendeiner Stelle der Turbine oder deren Dampfleitungen angebracht werden. Mitunter kann es zweckmäßig sein, das Heizelement in die Dampfleitung zwischen der Turbine und dem Kondensator oder ganz oder teilweise in den Kon-densator zu verlegen.The heating element can be placed anywhere on the turbine or its steam lines will. Sometimes it can be useful to place the heating element in the steam line between the turbine and the condenser or in whole or in part in the condenser relocate.

Das Element kann von dem Dampf kontinuierlich oder nur dann durchgeströmt werden, wenn die Turbine abgestellt ist. Im letzteren Falle kann die Vorrichtung, wie in Abb. 2 gezeigt, angeordnet sein, wo 21 den Dampfeinlaß und 24 die Zuleitung zu der Turbine bezeichnen, wobei 22 ein Ventil ist, das 21 entweder mit 23 oder mit 24 verbindet.The steam can flow through the element continuously or only when the turbine is switched off. In the latter case, the device, as in Fig. 2, be located where 21 is the steam inlet and 24 is the supply line to the Designate turbine, where 22 is a valve connecting 21 to either 23 or 24.
